Just noticed 'shadow lines' appearing on our TV. Its an LCD(?) that we've had about 4 months. They aren't always there and appear briefly displaced away from the image they shadow, or you get the odd 'smudge' flashing up every now and then. Predomiantly on the Left side.

I guess its the telly, but wondered if there was a known issue with Sky+ boxes? Will try running the cable into the Freesat but am worried the TV will have to go back.

wondered what i'd done then!!

have you tried altering the picture output on your sky box (to RGB/component often improves the picture – or if it's skyHD and the telly does 720whatever, then set to "posh")

Not changed anything AFAIK, its just started doing it.

Can you power it up with no signal and a black screen (i.e. unplug the sky box) – if there's something going on with the backlight then it could show up then.
I have a samsung that was a bit 'odd' but turning down the backlight a bit and upping the contrast a tad seemed to help. Or my retinas have failed in the same pattern…

You pervert Smudge flashes 😆

I had the image retention thing & sparkles on my telly which was 4 years old, John Lewis gave us a new one under guarantee
